A highly enantioselective synthesis of functionalized cyclopentanoids by a formal asymmetric (4+1) annulation strategy was developed. The methodology consists of a stereoselective cyclopropanation reaction between chiral sulfur ylides and 1,3‐dienes followed by a, in situ, stereospecific MgI2‐catalyzed rearrangement of vinylcyclopropanes. This method is distinguished by a remarkable compatibility with
通过形式的不对称(4 + 1)环空策略开发了功能化的环戊烷类化合物的高度对映选择性合成。该方法包括手性硫醚和1,3-二烯之间的立体选择性环丙烷化反应,然后进行原位立体定向MgI 2催化的乙烯基环丙烷重排。该方法的特点是与官能团具有显着的兼容性,并具有高度的立体控制。
